JavaScript
Web の言語を、基礎から非同期処理まで。
JavaScript is the language of the web. It runs in every browser, on servers with Node.js, and inside countless websites and games. This track takes you from your very first line to real interactive pages: values and logic, arrays and loops, functions and closures, objects and JSON, the DOM and events, and async code with promises, async/await and fetch.
Every lesson is short, hands-on and checked with quizzes, so you learn by doing.
